The specific embodiment
Further set forth concrete structure of the present utility model below in conjunction with accompanying drawing.
Shown in accompanying drawing 1,2,3, a kind of cyclone separator of dust catcher comprises dirt bucket 16, is arranged on first air inlet 5 on the described dirt bucket 16, is positioned at the dirt bucket bottom 15 of described dirt bucket 16 bottoms, the dirt barrel top cover 1 that is positioned at described dirt bucket 16 tops, a plurality of whirlwind awl 9 that is arranged in parallel, is separately positioned on second air inlet 91 on each described whirlwind awl 9, covers the whirlwind awl of boring 9 tops at each described whirlwind respectively and cover 8, be arranged on described dirt bucket 16 inside and be positioned at the primary filter net 10 of described second air inlet 91 upstreams.
Wherein, described first air inlet 5, primary filter net 10, dirt bucket 16, dirt bucket bottom 15 constitute primary cyclone, and described whirlwind awl 9 and whirlwind awl cover 8 and constitute secondary cyclone.
Described first air inlet 5 is circular, and the position is positioned in the middle of the described dirt bucket 16, and the axis of the axis of described first air inlet 5 and described dirt bucket 16 is vertical angle substantially; Described wind deflector 17 is connected with 5 assemblings of described first air inlet, fluid vertically enters dirt bucket 16 from first air inlet 5, under the guiding of described wind deflector 17, fluid has certain tangential initial velocity in described dirt bucket 16, thereby forms eddying motion along the inwall of described dirt bucket 16; Preferably, described wind deflector 17 increases gradually along the size of opening direction, and is made of one with described primary filter net 10.
As shown in Figure 4, described primary filter net 10 is coaxial with described dirt bucket 16, be divided into two parts are up and down arranged, its upper end has a plurality of equally distributed breeder tubes 101, preferably, the outboard end mask of breeder tube 101 has fillet, so that the fluid in the described dirt bucket 16 enters secondary cyclone smoothly by breeder tube 101; Its lower end has had the dust-break limit 102 of dust-break effect, enters secondary cyclone with the dust that stops separation, preferably, has the muscle position 103 of protrusion near the bottom on dust-break limit 102; The outer wall on described dust-break limit 102, described dirt bucket 16 and the described dirt bucket bottom 15 common dust storage chambers that form primary cyclone; The inwall on described dust-break limit 102 and the described dirt bucket bottom 15 common dust storage chambers that form secondary cyclone are sealed by sealing ring between two dust storage chambers.
Shown in accompanying drawing 5,6, a plurality of described whirlwind awls 9 are positioned at the inboard of described dirt bucket 16, and the top ends of the top ends of described primary filter net 10 and described second air inlet 91 is positioned at the sustained height position.Described whirlwind awl 9 is made of with other whirly awl 902~907 that becomes circumferential arrangement around it jointly the awl of the whirly in the middle of being positioned at 901, each whirly awl has second a tangential air inlet 91, sub-circular and the highly identical column part 92 of described second air inlet 91, tapered segment 93, dust fall mouth 94, described second air inlet 91 is arranged outwardly, and the peak of described second air inlet 91 and described first air inlet 5 topmost are consistent; Each whirly awl 901~907 is measure-alike, and evenly distributes by circumference; The outer wall of described whirlwind awl 9 has an outward extending muscle 94, and preferably, described whirlwind awl 9 and described primary filter net 10 are connected together by supersonic welding, and the muscle position 94 of extension forms the fluid passage with described primary filter net 10 upper inside wall.
